IMPROVEMENT IN VALVES FOR 'WATER-CLOSEIS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID MORRISON, of New York, in the county of New York, and State of New York, have invented a new and useful Improvement in Valves for Water-Closets; and I do hereby declare that the following is a full,'clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure I is a top view.

Figure 2 is a central vertical section.

Figure 3 is a top view of the plunger and hollow spindle.

The nature of my invention consists in so constructing a self-acting valve for water-closets that it will gradually close itself, and shut olf the water entirely after a sui'lcient quantity has passed through 'the bowl,

thus preventing any waste of water.

In the drawings, A represents the cylinder, in which are placed the valves; A the lower chamber, and A the upper chamber in the cylinder A; B, the pipes through 'which the water enters the chamber A; C, the

i pipe leading from the chamber A to the bowl; D, the solid plunger; E,the hollow spindle; Fthe base of the cylinder A. Gr, the guide in which the lower end of the hollow spindle E slides; H, a. spiral spring around the hollow spindle E, the lower end of which rests upon the` top of the base, F, and its upper end presses against the under side of the plunger D; I, the double-valve seat between the chambers A A"; J, the small valve in the hollow spindle E; K, the rod which eztendsfrem the top of the chamber A, up to the underside of the seat of the water-closet; L, a spindle on the top of the valve N; IVI, the valve in the chamber A, which rests on and ts over the spindle L; N, the large valve in the chamber A; O, the waste-pipe; P, the coupling on the waste-pipe O Q, the packing between the rod K and the tcp of the valve M.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Between the end of the supply-pipe B and the end of the pipe C, leading to the bowl, is placed a hollow cylinder, A. On opposite sides of this cylinder are hollow projections B C, and on their outer ends are cut screw-threads, and the pipes B and C are secured to them by couplings. The inside of the cylinder A is divided into two chambers A A, and between them is the doublevalve seat I. The bottom or base, F, of the cylinder is secured to the Hoor or in any suitable position, and in the top of it is an opening for the rod K to pass through, by which the valves are operated.v `The supply-pipe opens into the chamber A', and the pipe C leads from the chamber Al to the bowl. In the chamber A is suspended the plunger D, which is a part of the hollow spindle E. This plunger has packing which its against the sidesof'the chamber A. Inside of and below the plunger D, is the hollow spindle E, and on the top of it is the valve N; The upper end of the spindle E is screwed into the plunger D, and above the end of the spindc E, on the inside ol' the valve N, is a chamber in which is placed the small valve J, the stem of which rests in the bore oi' the hollow spindle E. The top of the spindle-E forms the seat of the valv'e'J. In the sides oi' the spindle E are holes a a, which open into the bore of the said spindle, and there are also holes b b in the chamber, inside of the valve N, which open into that portion of 'the chamber A above the plunger D., The lower end of the spindle-E rests in a guide or socket, G,in the base, F. On the upper end, and on one side of the spindle ELis cut a small groove, c, through which the water passes as the plunger rises in the chamber A. Over the tcp oi' the chamber` A" is placed a circular piece of India rubber,

or other suitable material, to prevent any leakage of water around the ro/d K. On one side of the cylinder A is a waste-pipe, O, which leads from the chamber A, and is secured to the cylinder A by a coupling, By

joining the waste-pipe in this manner, it obviates the necessity of cutting the pipe whenever it is desired to remove the cylinder or valves.

The operation of the valves is as fellows: Pressure is applied to the rod K, which forces the plunger and spindle down. As the plunger is being pressed down, it forces the water below it, in the chamber A', through the holes a a, into the bore oi' the hollow spindle E, and raises the valve J, which allows the water to pass into the chamber inside of the valve N, and

thence out through the holes Hfabove the plunger. When the rod K yhas reachedthe extent of its downward movement, the valve M rests .upon the upper side of the valve-seat I, and closes the aperture between the ehambers A and A, which prevents any water from passing into the bowl. The position ofthe valve J, during the downward movement of' the plunger, is shown in red lines. When the rod K is released from pressure, the spiral spring H acts against the under side of the plunger D, and forces it upward. As soon as the plunger begins to rise, the water above closes the valve J, which causes the water to pass down through the small groove .a in the valve-seat, causing the main valve to close very slowly. During the time the main valve N is ascending, the water is passing from the supply-pipe B into the chamber A', thence through the opening in the valveseat I tothe pipe C, leading into the bowl. The time required for closing the valve N is regulated 'by thesize of the groove c in the hollow spindle.

In a. valve constructed in this manner, it will 'ne seen that the water passes both ways through the same hole; also, that each time water passes through the hollow spindle it washes out any sediment that may have collected in the groove c. In the drawing, the valve N is represented as closed.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The plunger D, valve J, and hollow spindle E, with its groove c, substantially as shown and described.

2. The combination of the rod K, valves M and N, double-valve-seat I, plunger D, and spindle E, when arranged and operated substantially inthe manner shown and described.
